Laccase CAS 80498-15-3

Laccase is a copper-containing polyphenol oxidase, which usually exists in dimer or tetramer form. Laccase was first discovered by Japanese scholar Yoshi in purple gum tree paint, and subsequently found in fungi, bacteria and insects also exist laccase. At the end of the 19th century, G. B. etranel first isolated it as an active substance cured by raw paint and named it laccase. The main sources of laccase in nature are plant laccase, animal laccase and microbial laccase. Microbial laccase can be divided into bacterial laccase and fungal laccase. Bacterial laccase is mainly secreted from the cell, while fungal laccase is mainly distributed outside the cell, which is the most studied type at present. Although plant laccase plays an important role in the physiological processes of lignocellulose synthesis and resistance to biological and abiotic stresses, the structure and mechanism of plant laccase have been unknown.
